This invention relates to adjustable type guide for typewriters. Thetype lever is, in the course of time, worn ofi at the places where itcomes into contact with the guide. In consequence of the play caused bythis, the distance between consecutive letters and the straightness ofthe line are adversely afiected.

The present invention has theaim of overcoming this disadvantage. It hasfor its object an adjustable type guide, which, as a unit or with itstype shanks, can be displaced in the longitudinal direction of the typebody of the type lever which has been struck. Whenever the type lever isworn to the point of afiecting the typing, the type,

guide as a unit, or the type shanks, are adjusted higher or lower, i. e.in the longitudinal direction of the type body of the type lever whichhas been struck, so that the type lever can be guided at a place whichhas not been worn, without fault and without lateral displacement.

The adjustment device can be carried out in several ways. The drawingillustrates by way of an example two forms of application:

Fig. 1 shows a form of application in which the whole type body can beadjusted as a unit.

Fig. la is a lateral view of Fig. 1, partly in section.

Fig. 1b is a plan view of Fig. 1, and

Fig. 2 is a second form of application, in which a part which supportsthe guide shanks is adjustably arranged in the main body of the guide.

The guide it (Figs. 1 to 1b) acts, during the stroke of a type betweenits shanks c, as guide for the type lever 17.

If the type lever b is worn off at A, owing to repeated friction withthe walls of the guide shanks 0, so that on account of the thus createdplay the distance between the letters and the straightness of the typeline are adversely affected, .then the guide it is adjusted as a unit,inasmuch as, after the screws h are loosened, it is, with the help ofthe slots d adjusted vertically and/or horizontally in the longitudinaldirection of the type body. After this adjustment of the guide, the typelever will not come into contact with the guide walls at the place A butat the place B, and will again be correctly guided because a new and notworn part of the lever is being guided.

According to the form of construction shown in Fig. 2, the guide 11 isheld fast in the usual way by two screws h. The guide shanks 0, however,are in this case arranged on a special body i which is held in positionby means of a clamp screw 9, in an undercut groove f, cut out from thefront face of the guide (1. In this case therefore not the whole guideis adjusted in a longitudinal direction of the type body, but, afterloosening the screw 9, the guide shanks c are adjusted with their body2' in the guide d.

I claim:

1. An adjustable and fixable type guide for typewriters which comprisesa guide capable of being fixedly and permanently mounted on a support infront of a typewriter platen, an auxiliary member carrying a pair ofshanks mounted on said guide, said auxiliary member being capable ofvertical adjustment, and means for fixedly se curing said auxiliarymember in any adjusted position, whereby the guide shanks can be movedfrom a region adjacent to a worn portion of a type lever to a regionadjacent to an unworn portion of the type lever thereby insuring thecorrect guidance of the type lever to the typewriter platen.

the typewriter platen.
